I tried reading the article, but it seems to me that this is one of those cases where trying to simplify things to the point that a layperson could understand it has led to the whole thing not making sense to anyone anymore.

I appreciate the effort, since I don't know enough physics to understand the paper, but...well...

by sizing the crystals in a medium for the frequency of the sound,you can increase the predictability of a "phonon" a sound photon, this means you can reflect bend or move the heat, by having multiple layers of different size gaps, different frequencies naturally move there, so I could make a heat rectifier that turns chaotic heat into a series of planes of order

So heat->tiny coherent sound -> electricity or whatever

these are thermocrystals

these can absorb ambient energy(like body heat) and do much more work then a traditional thermionic cell, or sterling engine, because there is no required temp differential,

having a nose cone could reduce heat shielding to almost nothing, because you can move the heat to a point and then remove it.... TO make power!!!

having a rocket nozzle made of this means no more disposable rockets,having a computer chip = infinite overclock almost....

it just opens up many possibilities,

I think that matter is a separation of negative and positive mass, and the actual "energy" is the orbit spin speed of the particles(on another invisible plain), that is why particles fail / disappear @ zero energy
